Articular cartilage is a firm rubbery layer of smooth white connective tissue that covers the ends of bones. It provides a slick gliding surface for joints and acts as a cushion to keep the bones from rubbing. Cartilage can break down due to overuse or injury, which can lead to pain, swelling and stability problems with your joint. The situation can be exacerbated by the amount of weight – or loading – put on the joint, such as in the case of obesity. In some cases, an articular cartilage injury can heal with rest, but often the damage progresses over time and can eventually develop into osteoarthritis of the knee.
The video below is intended to give you a general overview of the procedures that can repair damaged articular cartilage. Your own surgery will be determined by the extent of the cartilage defect and the judgement of your surgeon.
